Axiom: it would be nice if more people filed reports directly into phabricator instead of posting them in random places from which they need to be moved.
Problem: people don't like to do things which require them to register an account. You can spend hours explaining them that registering takes few seconds, it doesn't work anyway: the human mind is not rational, they'll prefer spending multiple minutes or even hours explaining you how they don't have the time/will/whatever to register.
Solution: let people file reports without registering, then just tell them "please fill the contact form" so that they don't worry about learning what "report", "issue tracker", "phabricator" and stuff mean but instead just see something familiar, a text area to fill and submit. Sub-items:
- would be nice for the unregistered user to be later mergeable to a registered one as soon as the user logins, a bit like StackExchange does;
- of course initially this could only be a test, until we confirm we're not overrun with spam etc.
Evaluation: probably the number of non-WMF people creating reports over a month; IIRC, this number is stable since bugzilla times, but we don't have a specific measure, only what the monthly issue tracker report does.
I remember we mentioned this possibility in the past but I don't think it's currently tracked. In fact I think it was the only benefit I could see in Phabricator over Bugzilla when the comparisons were made, but maybe I'm misremembering, I didn't check Phabricator docs.
